Manager that can be used to track and notify
RemoteCommitListeners on remote commit events. If remote events
are enabled, this manager should be installed as a transaction listener on
all brokers so that it knows when commits are made.

addInternalListener

Adds an OpenJPA-internal listener to this RemoteCommitEventManager.
Listeners so registered will be fired before any that are registered
via addListener(org.apache.openjpa.event.RemoteCommitListener). This means that the external listeners can
rely on internal caches and data structures being up-to-date by the
time that they are invoked.
